A control configuration that performs a water spouting operation of a water spouting section for hand washing based on the operation of a toilet device has the following problems. The time it takes for a user sitting on a toilet seat to stand up after defecating, put on clothes, and move to a water spout for washing hands varies depending on the user. Therefore, the timing of discharging water for hand washing based on the operation of the toilet device may deviate from the desired timing of the user's hand washing.

Specifically, for example, in the case of a user who takes longer than usual to put on clothes after leaving the toilet seat, the time it takes to put on clothes will take longer to wash the hands. For this reason, the timing of water spouting for hand washing based on the operation of the toilet device is earlier than the timing desired by the user, and in some cases, the timing for discharging water for hand washing is not completed in time, causing the user to Hand washing may not be possible. On the other hand, if a user moves quickly after leaving the toilet seat and takes a shorter time than usual to wash their hands, the timing of water spout for hand washing based on the operation of the toilet device may be different from the user's desired timing. It is possible that the timing may be later than expected.

Therefore, even for users who take a relatively long time to wash their hands due to clothing, etc., or users who take a relatively short time to wash their hands, the water spout from the hand washing spout is sufficient. For example, it is conceivable to lengthen the water spouting time from the water spouting part for washing hands so that the water can be absorbed. However, increasing the time for discharging water from the water spout for hand washing is not preferable from the viewpoint of water conservation, since the amount of water wasted from the water spout increases accordingly.

In addition, by adopting an automatic faucet that detects the user's hand using sensors such as infrared sensors and Doppler sensors and automatically spouts water in the water spout for hand washing, control based on the operation of the toilet device is possible. Regardless, it becomes possible to spout water for hand washing. However, it is not preferable to employ an automatic faucet equipped with a sensor for detecting hands because there is a concern that the number of parts and cost will increase for the water spouting part for hand washing.

The present invention has been made in view of the above-mentioned problems, and has a configuration in which water is spouted from a hand-washing water spouting section based on the operation of a toilet device, and is adapted to accommodate different hand-washing timings depending on the user.

Water can be spouted from the area. This makes it possible to use the water spouted for hand washing efficiently, and also allows the hand washing section to perform a smooth hand washing operation.

Another aspect of the toilet system according to the present invention is that in the above-mentioned toilet system, the control unit includes a large flush mode and a small flush mode in which the toilet bowl is flushed using a smaller amount of flush water than in the large flush mode. and, when performing a toilet bowl flushing operation in the large flushing mode, the timing for starting water spouting from the water spouting part for hand washing is delayed than when performing a toilet bowl flushing operation in the small flushing mode. .

According to a toilet system with such a configuration, the timing of starting water discharge for hand washing can be changed depending on the washing mode of large washing and small washing, so for example, it is possible to change the time it takes to get dressed after using the toilet, or how to sit on the toilet seat. Water can be spouted from the water spouting part for hand washing at an appropriate timing depending on the detailed usage status of the toilet device by the user, such as presence or absence. As a result, efficient use of water for hand washing and smooth hand washing operation by the hand washing section can be effectively achieved.

Another aspect of the toilet system according to the present invention is that in the toilet system described above, the control unit starts the flushing operation of the toilet bowl before the timing at which the water spouting unit for hand washing starts discharging water.

According to a toilet system with such a configuration, it is possible to wash hands using the hand washing section after the flushing of excrement in the toilet bowl has started and even after the excrement has been flushed out of the toilet bowl. becomes. In other words, it is possible to avoid a situation where the user washes his/her hands using the hand washing section while excrement remains in the toilet bowl. This allows the user to wash their hands in a mentally refreshed state, and improves the feeling of using the toilet.

According to the present invention, in a configuration in which water is spouted from the water spout for hand washing based on the operation of the toilet device, it is possible to correspond to the timing of hand washing that differs depending on the user, etc., and the number of parts and number of parts for the water spout for hand washing can be adjusted It is possible to reduce wasted water without increasing costs, and to perform a good hand washing operation.

It extends horizontally toward the rear wall 7 side along the wall surface 6a. A portion of the hand wash drain pipe 55 extending from the cabinet 43 to the rear side extends below and parallel to the piping portion of the water supply pipe 10 for the hand wash section.

The hand wash drain pipe 55 has a trap pipe portion 55a which has a bent portion in the storage space 43a of the cabinet 43 with respect to a pipe portion extending downward from the drain port 42b, and is curved in a substantially “U” shape. The hand wash drain pipe 55 has a portion downstream of the trap pipe portion 55a curved at right angles to the folded piping portion forming the trap pipe portion 55a to form a horizontally extending portion. In the trap pipe portion 55a, a water seal is formed by the drainage, and foul odors, pests, etc. are prevented from entering through the drain port 42b.

The downstream side of the hand wash drain pipe 55 is connected to the drain trap of the toilet bowl 14. As a result, water discharged from the hand wash faucet 41 is discharged from the drain port 42b of the bowl portion 42a through the hand wash drain pipe 55 into the drain trap of the toilet bowl 14. Note that the downstream side of the hand wash drain pipe 55 may be connected to a predetermined drainage facility provided on the building side, for example from the side wall 6 side or the floor 5 side.

Of the water supply pipe 10 for the handwash section and the handwash drain pipe 55, the portion including the horizontal pipe portions arranged parallel to each other is covered by a pipe cover 58 provided on the right side of the cabinet 43 (on the rear wall 7 side). ing. The piping cover 58 is provided below the counter 45 so as to span the entire area between the cabinet 43 and the rear wall 7, has a rectangular cross-sectional shape, and extends horizontally. It is installed. The pipe cover 58 covers most of the handwash section water supply pipe 10 and the handwash drain pipe 55 arranged outside the cabinet 43. Note that a wire harness 53 and the like that connect the control section 20 of the toilet device 3 and the water supply valve unit 52 are also accommodated in the pipe cover 58 .

As described above, the toilet system 1 according to the present embodiment is a toilet system that cleans the toilet bowl 14, and includes the hand-wash faucet 41 as a water spout for hand-washing, the control of the flushing operation of the toilet bowl 14, and the hand-washing faucet 41. The control unit 20 controls the water discharge from the faucet 41. In such a configuration, the control unit 20 controls water discharging from the hand wash faucet 41 based on the flushing operation of the toilet bowl 14, and starts discharging water from the hand wash faucet 41 under control by the control unit 20. The timing is changeable.

The control unit 20 performs a large flush operation in which the toilet bowl flushing valve unit 26 is operated in a major flushing mode based on the operation of the major flushing button 28a of the remote controller 21, and a small flushing button 28b of the remote controller 21 as the flushing operation of the toilet bowl 14. Based on this, the toilet bowl flushing valve unit 26 is operated in the minor flushing mode to perform a minor flushing. Based on such a flushing operation of the toilet bowl 14, the control unit 20 controls the water discharge stop of the hand wash faucet 41.

Specifically, upon receiving an operation signal from the remote controller 21 based on the operation of the toilet flush button 28, the control unit 20 transmits a control signal to the toilet flush valve unit 26 based on the input of the operation signal, A cleaning operation of the toilet bowl 14 is performed. The control unit 20 determines the timing of the input of the operation signal from the remote controller 21 or the timing of the output of the control signal to the toilet flushing valve unit 26 when performing the flushing operation of the toilet bowl 14. (hereinafter referred to as "toilet bowl flushing timing").

The control unit 20 uses the control operation that specifies the toilet flushing timing as a trigger, and transmits a control signal to the water supply valve unit 52 at a predetermined timing based on the toilet flushing timing, and sets the water supply channel for handwashing to a state in which water is supplied to the handwashing water. Water discharge from the tap 41 is started. The control unit 20 that started the water spout continues the water spout for a predetermined period of time, and then controls the water supply valve unit 52 to stop the water spout. The automatic water discharging operation of the hand wash section 4 based on such a toilet flushing operation eliminates the need to operate the water discharge stop button 41b of the hand wash section 4, and maintains the cleanliness of the hand wash faucet 41, etc., resulting in sanitary conditions. It is preferable.

As described above, the control unit 20 is configured to vary the timing at which water is started to be spouted from the handwash faucet 41 (hereinafter referred to as "handwash water spouting timing") based on the flushing operation of the toilet bowl 14. . Here, the hand wash water discharging timing is, for example, the timing at which a control signal is output to the water supply valve unit 52 when the control unit 20 starts discharging water from the hand wash faucet 41.

In the graph shown in FIG. 5, the horizontal axis shows time, graph G0 shows the water spouting time (water spouting duration) in the toilet flushing operation, and graphs G1, G2, and G3 show the water spouting time (water spouting duration) in the hand washing water spouting operation. water discharge duration). Here, the flushing time of the flushing water during the toilet flushing operation corresponds to the time when the toilet flushing valve unit 26 is in the water-flowing state, and the water spouting time during the hand-washing water spouting operation corresponds to the time when the water-feeding valve unit 52 is in the water-flowing state. handle.

As shown in FIG. 5, when the toilet flushing timing is set to time t0 (0 seconds) and the handwashing water spouting timing is set to time ta, the control unit 20 changes the handwashing water spouting start time Δt, which is the time from time t0 to time ta. configured to be possible. For example, if the handwashing water spouting start time Δt is 0 seconds, time t0 = time ta, and as shown in graph G0 and graph G1, the handwashing water spouting timing (time ta1) is the same as the toilet flushing timing (time t0). . Further, when the hand washing water spouting start time Δt is time t2, as shown in graph G0 and graph G2, the hand washing water spouting timing (time ta2) is after time t2 has elapsed from the toilet bowl flushing timing (time t0). In addition, when the handwashing water spouting start time Δt is a time t3 that is longer than the time t2, as shown in graph G0 and graph G3, the handwashing water spouting timing (time ta3) is set after time t3 has elapsed from the toilet flushing timing (time t0). Become.

In this way, the control unit 20 is configured to be able to change the hand washing water spouting start time Δt. Note that the water spouting time of the handwashing water spouting operation, that is, the time Δs from the handwashing water spouting timing until the water spouting from the handwashing faucet 41 is stopped, is, for example, about several seconds to several tens of seconds, and can be configured to be changeable by the user. can. The control unit 20 controls the water supply valve unit 52 to turn the hand wash faucet 41 into a water-stop state after a predetermined period of time has elapsed from the hand wash water spouting timing.

As described above, in the configuration in which the handwash water spouting timing based on the toilet flushing timing is made variable by the control unit 20, the control unit 20 changes the timing at which water is started to be spouted from the handwash faucet 41 (handwash water spouting timing). It is configured so that it can be set as multiple possible patterns. That is, the control unit 20 is configured to be able to set and register a plurality of hand washing water spouting start times Δt depending on the user and the like.

The toilet device 3 is configured so that settings (adjustment details) for various functions of the sanitary washing device 15 can be registered for each user, and the settings include the handwash water spouting start time Δt. As shown in FIG. 4, the remote control 21 is provided with a plurality of user buttons 60 as an operation section for registering and calling up settings for various functions of the sanitary cleaning device 15.

In this embodiment, the remote control 21 has four user buttons 60, first to fourth user buttons 60a, 60b, 60c, and 60d, arranged side by side. Regarding the four user buttons 60, for example, in the case of a family of four, one user button 60 is assigned to each person for use. Note that one user may use a plurality of user buttons 60.

The hand washing water spouting start time Δt is set to, for example, 0 seconds, 15 seconds, 30 seconds, 45 seconds, 60 seconds, or the like. When the handwashing water spouting start time Δt is 0 seconds, the handwashing water spouting timing is the same as the toilet flushing timing. In other words, in this case, the hand wash faucet 41 starts discharging water at the same time as the toilet flush button 28 is operated. The settings for various functions of the sanitary cleaning device 15 are stored in a storage device such as a RAM in the control unit 20. The various functions of the sanitary washing device 15 that are subject to registration and calling include, in addition to the hand washing water discharging timing, for example, the strength of flushing water discharged from the nozzle 36, the position of flushing water spouted by the nozzle 36, the temperature of the toilet seat 18, etc. is included.

An example of an operating method and configuration for registering and calling various functions of the sanitary cleaning device 15 will be described. When registering, first, one of the plurality of user buttons 60 is selected and pressed. Here, it is assumed that the first user button 60a is pressed. After pressing the first user button 60a, the operator operates an operation button (not shown) provided on the remote controller 21 for adjusting the handwashing water spouting start time Δt, and sets the handwashing water spouting start time Δt to a desired time. Thereafter, by pressing a user setting button (not shown) provided on the remote control 21, registration is completed.

When calling up registered contents regarding various functions of the sanitary cleaning device 15, the first user button 60a of the plurality of user buttons 60 is pressed. When a user button 60 other than the first user button 60a is pressed, the contents registered in association with the pressed button are called up. In this way, the user button 60 serves as an operation section for instructing the control section 20 of the sanitary cleaning device 15 to read out user settings registered in advance.

In addition, in this embodiment, a plurality of user buttons 60 according to the number that can be registered are provided as an operation section for registering and calling up settings for various functions of the sanitary cleaning device 15. The present invention is not limited to such a configuration. The operation unit for registering and calling up settings may be, for example, a combination of a single user button and a plurality of number display units whose display changes each time the user button is operated. Furthermore, the number of registrations that can be made for various functions of the sanitary cleaning device 15 is not limited to four, and may be, for example, three or five.

As described above, the control unit 20 has a plurality of cleaning modes as control modes for the cleaning operation of the toilet bowl 14 according to the plurality of toilet bowl cleaning modes that the toilet bowl device 3 has. In such a configuration, the control unit 20 is configured to change the water spouting timing for hand washing depending on the washing mode. That is, the control unit 20 is configured to change the hand washing water spouting start time Δt according to the toilet bowl cleaning mode.

In this embodiment, the control unit 20 has a large washing mode and a small washing mode as washing modes for the toilet bowl 14. In such a configuration, when performing the flushing operation of the toilet bowl 14 in the large flushing mode, the control unit 20 delays the hand flushing water spouting timing than when performing the flushing operation of the toilet bowl 14 in the small flushing mode. That is, the control unit 20 is configured to make the hand washing water spouting start time Δt longer when performing a large wash than when performing a small wash. An example of such a control operation by the control unit 20 will be described using FIG. 6.

FIG. 6A shows a case where the control unit 20 performs deep cleaning. In the graph shown in FIG. 6A, the horizontal axis shows time, graph G11 shows the flushing time of flushing water in the toilet flushing operation, and graph G12 shows the water spouting time in the hand washing water spouting operation. As shown in FIG. 6A, in the case of deep flushing, the handwashing water spouting timing (time ta11) comes after a predetermined time t11, which is the handwashing water spouting start time Δt, has elapsed with respect to the toilet bowl flushing timing (time t0).

FIG. 6B shows a case where the control unit 20 performs a small wash. In the graph shown in FIG. 6B, the horizontal axis shows time, graph G21 shows the flushing water spouting time in the toilet flushing operation, and graph G22 shows the water spouting time in the hand washing water spouting action. As shown in FIG. 6B, in the case of small flushing, the handwashing water spouting timing (time ta12) is the same as the toilet flushing timing (time t0) (time t0 = time ta), and the handwashing water spouting start time Δt is 0 seconds. It becomes. Note that in the small flush, the amount of flush water supplied to the toilet bowl 14 is smaller than in the case of the large flush, and the flushing time (time Δu) of the flush water in the toilet bowl flushing operation is shorter than that in the large flush.

As described above, in the case of a large flush, water spouting from the hand faucet 41 is started after a predetermined time t11 has elapsed from the toilet flushing timing, and in the case of a small flush, water spouting from the hand faucet 41 is started at the same time as the toilet bowl flushing timing. is started. Adjustment of the water discharge timing for hand washing using the washing mode is based on the usage status of the toilet 2 by the user as described below.

In the case of deep flushing, it takes a relatively long time for the user to get dressed after relieving himself, so the hand flushing water spouting timing is shifted to a later time than the toilet bowl flushing timing. In other words, if the time it takes for the user to get dressed etc. is relatively long, the time from the end of using the toilet device 3 to the start of the hand washing operation will be correspondingly longer. A considerable amount of time is required. For this reason, for example, time t11, which is the handwashing water spouting start time Δt, is secured as the time from when the user leaves the toilet seat 18 (stands up) until the user starts the handwashing operation using the handwashing section 4. Although this is just an example, the length of time t11 is, for example, about 30 seconds.

On the other hand, in the case of a small flush, the time for the user to get dressed after relieving himself is relatively short, so water spouting from the hand wash faucet 41 starts at the same time as the toilet bowl flushing timing. That is, in the case of a small wash, the time for the user to get dressed is relatively short, and the time from the end of using the toilet device 3 until the start of the hand washing operation is short, so the hand washing water spouting start time Δt is provided. Instead, the water spouting timing for hand washing is the same as the timing for flushing the toilet bowl. The usage situation for such a short flush is assumed to be a case where the short flush is performed after the user relieves himself without sitting on the toilet seat 18.

In the example shown in FIG. 6B, the hand washing water spouting timing is the same as the toilet flushing timing (hand washing water spouting start time Δt=0 seconds), but these timings are not limited to being simultaneous. In the case of a small flush, for example, water spouting from the hand wash faucet 41 may be started immediately after the toilet bowl flush timing. That is, in the case of a small wash, for example, a time shorter than the time t11 in the case of a large wash may be secured as the hand wash water spouting start time Δt. Furthermore, in the case where the sanitary washing device 15 is configured to perform an eco-washing, the control of the water spouting timing for hand-washing may be performed using the same control as during the eco-washing, for example. You may also do so.

Regarding the relationship between the toilet bowl flushing timing and the handwashing water spouting timing, the control section 20 may be configured to start the flushing operation of the toilet bowl 14 before the handwashing water spouting timing. In other words, the toilet flushing timing is set to be a predetermined time before the hand flushing water spouting timing.

Specifically, as shown in FIG. 6A, for example, in the case of deep flushing, a predetermined period of time that is the hand flushing water spouting start time Δt with respect to the toilet flushing timing (time t0) based on the signal from the seating detection sensor 23, for example. The configuration is such that the hand washing water spouting timing (time ta11) comes after t11 has elapsed. Although the example shown in FIG. 6A is for a large flush, the same applies to a small flush, for example, in a configuration in which the hand flush water spouting timing occurs after a predetermined period of time has elapsed from the toilet bowl flushing timing based on the operation of the remote control 21, that is, the hand flush water spouting timing. A configuration may be adopted in which the start time Δt is secured.

Further, as a configuration in which the hand-washing water spouting timing occurs after a predetermined period of time has elapsed from the toilet bowl flushing timing, for example, as shown in FIG. 7A, the hand-washing water spouting timing may be set to the timing when the flushing operation of the toilet bowl 14 is completed. . That is, in this configuration, as shown in FIG. 7A, time tb, which is the end timing of the toilet flushing operation, is time ta31, which is the hand washing water spouting timing. In other words, the time t31, which is the hand wash water spouting start time Δt, is the same as the flushing water spouting time of the toilet flushing operation, that is, the time Δu from the toilet flushing timing until the supply of flushing water to the toilet bowl 14 is stopped. . Note that the timing at which the supply of flush water to the toilet bowl 14 is stopped, that is, the timing at which the toilet bowl flushing operation ends, is, for example, determined by the control unit 20 communicating with the toilet flushing valve unit 26 to close the toilet flushing valve unit 26. Corresponds to the timing when the signal was sent.

As another pattern, for example, as shown in FIG. 7B, a configuration in which the hand wash water spouting timing occurs after a predetermined time has elapsed from the toilet bowl flushing timing is such that the hand wash water spouting timing occurs after a predetermined time elapses from the timing when the flushing operation of the toilet bowl 14 is completed, for example, as shown in FIG. 7B. It may be possible to have a configuration in which That is, in this configuration, as shown in FIG. 7B, the time after a predetermined interval time Δv has elapsed from time tb, which is the end timing of the toilet flushing operation, is time ta32, which is the water spouting timing for hand washing. In other words, in this configuration, the time t32, which is the hand wash water spouting start time Δt, is the sum of the time Δu from the toilet flush timing until the supply of flush water to the toilet bowl 14 is stopped and the interval time Δv. . In the graphs shown in FIGS. 7A and 7B, the horizontal axis indicates time, graph G31 indicates the flushing time of flushing water in the toilet flushing operation, and graph G32 indicates the discharging time of the flushing water in the hand washing operation.

As described above, in the toilet system 1 of the present embodiment, a configuration is appropriately adopted in which the toilet bowl flushing timing is set earlier than the hand wash water discharging timing, regardless of the cleaning mode of large flushing or small flushing. In such a configuration, the length of the hand washing water spouting start time Δt is not particularly limited.

Regarding the usage of the toilet system 1 according to the present embodiment having the above configuration, a series of operations of the toilet system 1 based on the user's operations will be explained using the flowcharts shown in FIGS. 8 and 9. .

First, the first usage mode will be described using FIG. 8. In the first usage mode, the user sits on the toilet seat 18 and relieves himself, and a deep flush is performed as a cleaning operation of the toilet bowl 14, and the toilet bowl cleaning operation is automatically performed based on the sensor output of the seating detection sensor 23. This is an example of a cleaning operation.

As shown in FIG. 8, the user enters the toilet 2 (S10) and sits on the toilet seat 18 with the toilet lid 19 open (S20). Here, the toilet lid 19 is opened automatically based on the sensor output of the human body detection sensor 22, or manually opened by the user. In step S20, the seating detection sensor 23 detects that the user is seated, and the control unit 20 detects that the user is seated.

The user seated on the toilet seat 18 relieves himself (S30), and after finishing relieving himself, he leaves the toilet seat 18 and stands up (S40). Here, the seating detection sensor 23 detects that the user leaves the seat, and the control unit 20 detects that the user leaves the seat.

After the control unit 20 detects that the user leaves the seat, cleaning of the toilet bowl 14 is automatically started after a predetermined period of time has elapsed (S50). That is, the control unit 20 operates the toilet bowl flushing valve unit 26 in the deep flushing mode to supply flushing water to the toilet bowl 14. After the flush water discharging time (for example, see time Δu in FIG. 6A in FIG. 6A) for the toilet flushing operation in the case of large flushing has elapsed from the toilet flushing timing, the control unit 20 controls the operation of the toilet flushing valve unit 26 to supply water to the toilet 14. The supply of flush water is stopped, and flushing of the toilet bowl 14 is completed (S60).

On the other hand, the user who left the seat in step S40 puts on his clothes (S70), and then washes his hands in the hand washing section 4. Here, the control unit 20 causes the water supply valve unit 52 to pass after the handwash water spouting start time Δt (for example, time t11 shown in FIG. 6A) in the case of large flushing has elapsed from the toilet flushing timing of the toilet flushing operation in the large flushing mode. The state is set to water, and hand washing faucet 41 starts discharging water for washing hands (S80). In other words, the hand-washing water spouting timing comes based on the toilet bowl flushing timing. After that, the control unit 20 turns the water supply valve unit 52 into a water stop state and stops the handwash faucet 41 from discharging water for handwashing after the water spouting time of the handwashing water spouting operation (for example, see time Δs in FIG. 5) has elapsed from the handwashing water spouting timing. (S90). The user who has finished washing his hands using the hand washing section 4 leaves the toilet 2 (S100).

Next, the second usage mode will be described using FIG. 9. In the second usage mode, the user relieves himself (urinates) without sitting on the toilet seat 18, and a small flush is performed as a flushing operation of the toilet bowl 14, and the toilet flushing operation is performed by the user using the remote control 21. This is an example of a toilet bowl cleaning operation based on the operation of the cleaning button 28b.

As shown in FIG. 9, the user enters the toilet 2 (S110) and relieves himself with the toilet lid 19 open (S120). Here, the toilet lid 19 is opened automatically based on the sensor output of the human body detection sensor 22, or manually opened by the user.

The user who has finished relieving himself puts on his clothes (S130), and then presses the small wash button 28b of the remote control 21, which serves as a wash switch (S140). When the small flush button 28b is pressed, cleaning of the toilet bowl 14 is started (S150). That is, the control unit 20 operates the toilet bowl flushing valve unit 26 in the small flushing mode to supply flushing water to the toilet bowl 14. After the flush water discharging time (for example, see time Δu in FIG. 6B) for the toilet flushing operation in the case of small flushing has elapsed from the toilet flushing timing, the control unit 20 controls the operation of the toilet flushing valve unit 26 to supply water to the toilet 14. The supply of flush water is stopped, and flushing of the toilet bowl 14 is completed (S160).

On the other hand, the user who presses the small wash button 28b in step S140 washes his hands in the hand washing section 4. Here, the control unit 20 sets the water supply valve unit 52 to a water flow state at the same time as the toilet flushing timing of the toilet flushing operation in the small flushing mode, or after a predetermined hand flushing water start time Δt, which is shorter than in the case of the major flushing, has elapsed, The hand washing faucet 41 starts discharging water for washing the hands (S170). After that, the control unit 20 turns the water supply valve unit 52 into a water stop state and stops the handwash faucet 41 from discharging water for handwashing after the water spouting time of the handwashing water spouting operation (for example, see time Δs in FIG. 5) has elapsed from the handwashing water spouting timing. (S180). The user who has finished washing his hands using the hand washing section 4 leaves the toilet 2 (S190).

According to the toilet system 1 according to the present embodiment having the above-described configuration, in the configuration in which water is discharged from the hand wash faucet 41 based on the operation of the toilet device 3, it is possible to correspond to different hand washing timings depending on the user etc. Therefore, it is possible to reduce wasted water without increasing the number of parts or cost of the hand-wash faucet 41, and to perform a good hand-washing operation.

In the toilet system 1 according to the present embodiment, the timing at which the hand wash faucet 41 starts discharging water can be changed based on the flushing operation of the toilet bowl 14. In other words, the toilet system 1 is configured to be able to change the hand flush water spouting start time Δt, which is the time from the toilet bowl flushing timing to the hand flush water spouting timing.

With such a configuration, it is possible to match the timing of hand washing water discharge based on the flushing operation of the toilet bowl 14 to the desired timing when the user wants to wash his hands. As a result, a situation may occur in which it is not possible to wash hands because the water is not spouted in time from the handwash faucet 41, or conversely, the time spent waiting for water to be spouted from the handwash faucet 41 becomes longer, or the water for handwashing may flow unnecessarily. can be restrained from doing so.

In other words, users who take a long time to get dressed can set the hand-washing water spouting timing relatively late, and users who do not take much time to get dressed can set the hand-washing water spouting timing relatively early. Hands can be washed reliably in accordance with the water discharged from each handwash faucet 41. Therefore, for example, it is not necessary to make the water discharge time from the hand wash faucet 41 longer than necessary in order to meet the usage conditions and preferences of multiple users, and it is possible to suppress wasted water and to save water. It becomes possible.

In addition, the hand wash faucet 41 does not use an automatic faucet that detects the user's hand with a sensor such as an infrared sensor and automatically spouts water, but instead performs water spouting operation according to the user's movements in the toilet 2. It becomes possible to do so. For this reason, it is possible to prevent or suppress increases in the number of parts, costs, and complexity of the structure of the device configuration of the hand wash faucet 41.

Furthermore, in the toilet system 1 according to the present embodiment, the control unit 20 is configured to be able to set the hand-washing water discharging timing as a plurality of switchable patterns.

According to such a configuration, multiple users can individually set the handwashing water spouting timing, so multiple users can use the handwashing section 4 at a handwashing water spouting timing that suits their preference. . This makes it possible to improve the usability of the hand-washing section 4 and to efficiently use the water spouted from the hand-washing faucet 41.

Further, in the toilet system 1 according to the present embodiment, the control unit 20 has a plurality of cleaning modes as control modes for the cleaning operation of the toilet bowl 14, and is configured to change the hand wash water spouting timing depending on the cleaning mode.

According to such a configuration, the timing of water spouting from the handwash faucet 41 can be changed according to the flushing mode of the toilet bowl 14, so that the water spouting from the handwash faucet 41 can be performed at an appropriate timing according to the usage status of the toilet device 3 by the user. It can be performed. This makes it possible to use water spouted for hand washing efficiently, and also allows the hand washing section 4 to perform a smooth hand washing operation.

Furthermore, in the present embodiment, the control unit 20 has a large washing mode and a small washing mode as the washing modes, and when performing a large washing in the large washing mode, it is easier to wash by hand than when performing a small washing in the small washing mode. It has a configuration that delays water discharge timing.

According to such a configuration, the water discharge timing for hand washing can be changed depending on the washing mode of large washing and small washing, so for example, the time taken to put on clothes after using the toilet, whether or not to sit on the toilet seat 18, etc. Water can be spouted from the hand wash faucet 41 at an appropriate timing depending on the detailed usage status of the toilet device 3 by the person. Thereby, efficient use of water for hand washing and smooth hand washing operation by the hand washing section 4 can be effectively achieved.

Furthermore, in the toilet system 1 according to the present embodiment, the control unit 20 is configured to start the flushing operation of the toilet bowl 14 before the hand flush water spouting timing.

According to such a configuration, it is possible to wash hands using the hand washing section 4 after the cleaning of the excrement in the toilet bowl 14 has started, and even after the excrement has been flushed out from the toilet bowl 14. becomes. In other words, it is possible to avoid a situation where the user washes his hands using the hand washing section 4 with excrement remaining in the toilet bowl 14. Thereby, the user can wash his hands in a mentally refreshed state, and the feeling of using the toilet 2 can be improved.

In particular, in a configuration where the toilet flushing timing occurs before the hand flushing timing, the hand flushing timing is the timing at which the toilet flushing operation ends, from the perspective of ensuring water pressure for both the flushing water for toilet bowl flushing and the water spouting water for hand washing. It is preferable to do so at the same time as or after the end timing. That is, it is preferable that the hand-washing water spouting timing is after the time when the flushing water spouting time of the toilet bowl cleaning operation (for example, see time Δu in FIG. 6A) has elapsed from the toilet flushing timing. Note that FIG. 7A shows a case where the hand-wash water spouting timing is the same as the end timing of the toilet bowl flushing operation, and FIG. 7B shows a case where the hand-washing water spouting timing is after the end timing of the toilet bowl flushing action.

With this configuration, the supply of flush water to the toilet bowl 14 and the discharge of water from the hand wash faucet 41 can be separated in terms of time, and a situation where these are performed at the same time can be avoided. As a result, water is supplied to the toilet bowl 14 in a configuration in which water is supplied to the toilet bowl device 3 and the hand basin portion 4 through the water supply pipes branched from the branch faucet 8, that is, the water supply pipe for the toilet bowl device 9 and the water supply pipe for the hand basin portion 10.
